Revealed is the 10th episode in Season 3 of H2O: Just Add Water.


While swimming in underwater, Bella finds a shell at the bottom of the ocean. She gives it to Will, telling him that she found it on the beach while she was swimming. Sophie becomes jealous of Will's relationship with Bella. Will checks to the Internet and finds out that the shells are only at the bottom of the ocean, so he demands Bella an explanation from where the shell came to the beach. Cleo and Rikki warn Bella to back off from Will as they know he's on the trail of their mermaid secrets. It's difficult for her as Will's becoming more intrigued by Bella and his increasing interest is making her feel a relationship may finally happen between them. Bella's left with no option but to stop seeing Will. Unfortunately, the directive comes too late as a close encounter with water leads Will to recognize Bella's secret and expose her as a mermaid! Bella's left on tenterhooks when Will stalls at keeping his incredible discovery private. Bella prepares for the worst at that night's gig at the Rikki's Café, but Will pledges to keep her secret – only a relationship between them appears unlikely for the minute. Meanwhile, Sophie becomes interested in the shell. Rikki comes to Will's shed while Cleo tries to keep Sophie away from the shed. Rikki finds the shell, but Sophie comes back to the shed and Rikki destroys the shell by heating it in the nick of time.

  • When the girls were transformed in the Mako Island pool they didn't turn into mermaids until twelve hours after their exposure. In the Irish pool, Bella transformed immediately.


Will: Where'd you get that?

Bella: Can you keep a secret? The Octopuses Garden. (Will looks confused) It's a joke.
